Abstract: A child booster seat includes a seat body having a cavity wall that confines a receiving cavity and that is formed with an opening. The child booster seat further includes a strap including a first end segment and a second end segment, and a coupling member attached to the second end segment. The strap is configured to couple with the seat body in a manner that the first end segment is retained in the receiving cavity and the second end segment is disposed to be extended through the opening in the seat body to dispose the first coupling member outwardly of the receiving cavity. The coupling member is connected releasably to the seat body so that the strap is operable to bind the seat body to the chair.

Abstract: A child booster seat includes a seat body, a seat base coupled to and vertically movable relative to the seat body, and a height-adjustment mechanism mounted between the seat body and the seat base. The height-adjustment mechanism includes a support structure mounted co-movably to the seat body and formed with a plurality of positioning holes that are vertically spaced apart. The height-adjustment mechanism further includes a latching component coupled movably to the seat base. The latching component includes a stop piece for engaging a selected one of the positioning holes to releasably lock the seat body at a desired height relative to the seat base. The height-adjustment mechanism also includes a manually operable part for moving the stop piece away from the positioning holes to release locking engagement between the seat base and the seat body.

Abstract: A foldable child booster seat includes a seat base, a backrest, a support unit, and a tray. The seat base includes a seat portion having a seating surface, and a pair of armrests respectively disposed at left and right sides of the seat base. The backrest is mounted foldably to the seat base. The support unit is movably coupled to the seat base to permit height adjustment of the seat portion relative to the support unit. The tray is removably mountable to a selected one of the seat base and the support unit to dispose the tray in a selected one of a state of use and a stowed state.

Abstract: A child booster seat includes a seat base, and an armrest support coupled to the seat base and formed with an installation space that opens upward. The armrest support has a wall confronting the installation space and formed with a plurality of restraining parts located at different heights of the armrest support. The child booster seat further includes an armrest assembly including a latching component having a tongue board that extends into the installation space and that is movable vertically within the installation space and a stop piece that projects from the tongue board for engaging selectively the restraining parts, and an armrest component coupled to the tongue board and vertically co-movable with the tongue board relative to the armrest support.
